Remove the toe plate in front of the refrigerator, below the doors.Check the coils under there to see if they need to be vacuumed out. Also check the condenser fan in back near the compressor to see if it's running.

You may be able to see if the condenser fan motor running by looking through the condenser coils at the front of the refrigerator, but if it's dirty it would be a good idea to pull the refrigerator out and remove the back so you can vacuum it out back there too.

Fan motor was not running. After I vacuumed the coils out and cleaned the fan blade the fan motor started working again.I have heard the refrigerator cycle on and off a few times now. Thanks for the help.
